RTP Explained
The RTP meaning is simple. It is the Return To Player and is based on a basic calculation. It shows the amount of money that comes out of a machine compared to the amount of money that goes in. And it is shown as a percentage. The RTP is always less than 100%. And the difference between the RTP and 100 is what the house takes home.
Let’s take a look at an example. Say a slot takes in £1000 and it has an RTP of 95%. Theoretically, the game should pay out £950. But that does beg the question why you would play a game that pays out less that it takes in?
The key here is that this figure does not apply to each and every spin. It is calculated over many thousands of spins over a long time period. So while a game may only pay back 95% of its cash, it doesn’t mean that you can’t win big when you hit the spin button. Individual wins are regulated by a random number generator. So you never know what the outcome might be when you play.
How high should the RTP be?
Even though the RTP isn’t a definitive indicator of what you’ll win each time, it does provide a useful reference. It’s pretty easy to see when a game isn’t giving players a fair crack of the whip. So you can always decide to avoid low RTP games if you feel that it isn’t in keeping with the gambling spirit.
As for how high it should be, that’s a matter of opinion rather than regulation. As a rough average, most slots in the UK will come in around 95-96%. But there are many that fall short of this and some that go above and beyond.
What we’re interested in today are the heroes that provide superb RTPs.
Microgaming slots with high RTP
Microgaming has been creating some world class games for the last couple of decades and is constantly adding to its list of best payout slots. They have a fantastic range of titles with a host of different themes. They’re responsible for the biggest pooled prize series in the industry and also have a hand in creating some of the best payout casino games.
Couch Potato – 97.43%
If stripping everything back to the bare bones was Microgaming’s aim, then they certainly hit the mark! This game offers just one payline with 3 reels and the most basic symbols that you’ll find on any slot.
The sound effects won’t have you dancing in your seat and the overall feel struggles to create too much excitement. So what does it have going for it? Big money. Potentially.
There aren’t any bonus features as such. Instead, you get some handy multipliers thanks to the couch potato symbols. 1 of them pays 5x the win combo, 2 of them raise it up to 25x. And 3 sees you land the jackpot. And this could be as much as 15 grand if you are playing the highest stakes of £3 per spin.
The game has high volatility which means that your balance will take a bit of a battering while you play. But the flip side of that is that every so often, a big win will emerge and hopefully see you fly into profit again.
Frozen Diamonds – 97%
This game is up there with the best payout online slots. It combines the extremely popular gems theme with some top payouts and a nice cascading reels system. And it’s all set perfectly into an icy backdrop with all the symbols being frozen in their individual blocks. Any winning combos disappear from the game board and new ones take their place. This gives you an extra chance to create more wins with the replacement symbols.
3 consecutive wins sees a few free spins come your way, which is a nice touch. Most games opt for bonus symbols to trigger this type of feature so it’s always good to see a little variety. During this feature, you’ll get 2 or 3 bonus wilds added to the last reel to help enhance your chances of winning. If you land another 3 wins in a row during a free spin, then you’ll have another spin with a 2x multiplier added to the end of your tally.
It’s a top game with lowish volatility so you can expect lots of action and plenty of low value wins while you wait for something bigger.
Reel Thunder – 96.95%
Another basic game from Microgaming that aims to remove any complications from the slots entertainment. There’s a fun cartoon biker theme with lots of bike trip related symbols and appropriately simple sound effects.
There aren’t any free spins or multipliers to look out for. So what you see is what you get. It’s a basic game with a decent RTP that can deliver some good wins if it’s in the right mood. There are 9 win lines across 3 rows and 5 reels. And you’ll also find a wild symbol jumping in to help out where it can. But that’s about as technically advanced as the game gets, unfortunately.
That said, it is still a lot of fun to play and has the potential to kick out a 90,000x win. So it could be worth a punt if you’re feeling lucky.
NetEnt slots with high RTP
NetEnt is another huge name in the industry and was recently taken over by Evolution in a £1billion+ buyout, which shows just how big they’ve become in recent years. They too have a huge progressive jackpot series and loads of classic table games that are always in high demand. But their real forte comes in the slots niche. Not only do they have some of the most popular games ever created in their arsenal but also a handful of high rtp slots too.
Mega Joker – 99%
It doesn’t matter how old this game gets, it never fails to appear in every list of best RTP slots. It was one of the first to breach the 99% mark and continues to draw in a big crowd partly thanks to this notoriety.
The classic feel of a land-based fruity will strike a chord with those who love to play on the casino floor. There’s nothing outlandish about the mechanics and doesn’t take long to get to grips with everything on display. Even though there isn’t a specific bonus round to aim for, the game does have a trick up its sleeve.
Winning prizes gives you the chance to risk the cash you’ve won by spinning the reels on the super meter board which sits above the regular reels. Here, you can find some massive payouts. And the chance to do this comes along fairly frequently which makes this game all the more alluring for players.
You’ll also notice the jackpot prize ticking upwards during your session. This progressive payout will turn up every so often so keep your fingers crossed for the big windfalls.
Jackpot 6000 – 98.86%
Now we’re not ones for accusing a game provider of cutting corners. However, this game is visually almost a carbon copy of the Mega Joker slot so fans generally prefer one or the other as a matter of principle. However, we have to say that it is near the front of the queue with the best payout slots.
But even though the machine looks pretty very similar and the sound effects are pretty much identical, there are some notable differences when it comes down to the nitty gritty. For a start, the game is much more basic than its counterpart. There isn’t a double set of reels but instead the super meter lets you use your winnings to play for a mystery prize.
There is also a gamble function that can help produce some incredible wins. To use this feature, you simply need to select heads of tails when you want to gamble any cash. You can keep going until you decide to collect or you lose. Choose wisely!
Kings of Chicago – 97.8%
If you’re looking for one of the best slot machines to play, then why not try Kings of Chicago. This game mixes video slots and poker together in one fantastic experience. The reels spin across a poker table and you win hands to land the prizes. It’s a unique take on a slot that has had fans engrossed for a while.
There are 3 rows of 5 cards and with just 5 paylines. It’s super simple to get the hang of. And the different hands are clearly shown to make it possible for even the greenest of card players to work out.
Payouts aren’t as regular as you might want though. And this is due to the high volatility. But the flip side of the coin is that there are some big wins to come across throughout the game. So play your cards right and you could walk off with a decent haul. This is definitely a classic Netent casino game!
Playtech slots with high RTP
Playtech is responsible for some cracking games. And as you’ll see, this includes one of the highest payout online slots around. They’ve been in business for many years and have built up a superb reputation.
Goblins Cave – 99.32%
One of the highest RTP casino slot machines is Goblin’s Cave. It has a treasure theme with 3 reels and plenty of added extras to keep you waiting with anticipation. And one of it’s main pulls is that it brings back the old ‘hold’ function that many of us remember fondly from our times in the arcade. Simply hold the reels that you want to keep and the game will respin. If any wins match up, then you get a prize.
Don’t expect to have your mind blown by the graphics or any animated touches. This game keeps it basic but yet it is still one of the best slot games to win top prizes. And the lack of clever features helps to keep things simple.
There are wild symbols which is kind of the least you could ask for from a video slot. In addition, there is also a bonus feature that is triggered when the lantern symbols turn up. Here, you’ll bag yourself an instant win by picking one of the treasure chests that you see. It could be a small prize or it could be something truly magical.
Golden Tour – 97.71%
One of the highest slots RTP is available on this unusual take on a slot. Not in the sense that it functions differently but in the golf theme that you don’t often find. There are 5 reels and 3 rows with various golfing tributes acting as symbols during the base game. You’ll find golf balls, clubs, carts and pints of lager too! And then there are the scatters which take on the various animal images that you might find while out playing a round.
Keep your eyes open for the golden golf balls that act as wilds and can create some astonishing winning combos. As a result of landing these, you could see the top payout of 2,000 coins.
The gopher, ducks and catfish symbols will unlock the bonus round, which is a fancy kind of ‘pick a win’ game. You can choose from a number of clubs before the golfer takes aim and lands a hole in one. You then get to see what prizes you have won.
It’s a nice take on a modern video slot. Just don’t expect jaw dropping graphics from this basic machine. Then again, some of the best payout slots are famously very similar in their approach.
8 Treasures 1 Queen – 97.29%
The 8 Treasures 1 Queen slot doesn’t seem like anything out of the ordinary at first glance. There are 5 reels with the super 243 win ways mechanism, which is certainly attractive. But this Chinese themed slot goes further than this. As many games do in this genre, the 8 treasures game presents a host of features like free spins and the Money Shot award with 10,000x wins available.
Scatter symbols get you a place in the free spins round. And here you’ll find between 8 and 28 bonus spins on offer. As an added extra, the middle reel turns into a stacked wild for the duration. So hope for some awesome wins at this point.
The money shot symbol can fall on the last reel at the end of 4 matching symbols. When this happens, you will see returns of up to 10,000x making this one of the best payout slots with a top RTP as well.

Columbus – 97.03%

Jackpot Diamonds – 97%

The reasons RTP matters
